The transportation of high-temperature medium places higher specifications within the construction, components and auxiliary program in the pump. Let's discuss the cooling requirements of various temperature variations and the corporation's relevant pump variety:
1. For media with a temperature lessen than a hundred and twenty°C, there is frequently no Specific cooling program, and also the medium alone is employed for lubrication and cooling. Including DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (protection volume of shielded motor need to exceed H grade when around ninety°C); and DFCZ typical type and IH chemical pump can use temperature to undertake suspension structure The higher limit is a hundred and forty°C ~ one hundred sixty°C; IHF lining fluorine pump can be used as many as two hundred°C; only CQB standard magnetic pump use temperature will not exceed a hundred°C. It truly is worth mentioning the medium that is straightforward to crystallize or contains particles must be equipped that has a sealing surface flushing line (intended with the interface).
two. For mediums above one hundred twenty°C and below 300°C, a cooling chamber shall be delivered within the pump address. The sealing chamber shall also be linked to the coolant (with double mechanical seal), in the event the coolant just isn't permitted to penetrate into the medium. It should be taken just after cooling its very own medium (is often realized by basic warmth exchanger).
3. For high temperature medium earlier mentioned three hundred°C, not just the pump head portion really should be cooled, but in addition the suspension bearing chamber really should be equipped having a cooling process. The pump composition check here is generally in the form of a central assist. The mechanical seal is if possible a metallic bellows type, but the value is substantial ( The worth is more than 10 instances that of a standard device seal).
